Answer:
Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotides.
Explanation:
DNA replication occurs to make exact copy of original DNA. Transcription of genetic information to an intermediate mRNA occur after replication after which we have translation of genetic information into amino acids.
In the process of replicating DNA error can occur and then enzymes proofread the work for errors. Enymes DNA polymerase proofs read the replication,removes and replace the nucleotide base from where error occurs. It proof read after the DNA replication has occured.
This enzyme is also involve in DNA replication.
Answer:
The correct answer is - option C. alligators; their tails dig holes that hold water during times of drought, and this water is used as a source for drinking water by many species.
Explanation:
Beavers are keystone species as they help other species to get habitat and also help plants to grow by the holes or dams they make. Kudzu is a keystone species of an ornamental plant which lowers the soil erosion in their abundance.
Red cocaded woodpecker is a keystone species as they create pits in the pine trees that are helpful for other species to live.
Alligators also keystone species but not for digging holes and hold water but the influencing the prey and maintaining the animals in the ecosystem.
Answer:
a) By repeating trials during an experiment
Explanation:
In science, repetition during experimentation is extremely important and fundamental. By repeting experiments, the researcher ensures that results are reliable and not due to a single factor or coincidence. If the same result is observed after several repetitions, then it could indicate that x factor is responsible for x result.
After this observation, the researcher will be able to analyze data statistically and discuss it in order for other scientists to repeat this methodology and explain a specific phenomenon accurately and thoroughly.
What are the vocab words?
The fusion of the vesicular membrane with the axonal membrane begins when ___cacium__ enter the cell through ____propagation of an action potential to the presynaptic membrane______, resulting in __________temporary ion chain nurotransmitters
When an action potential arrives at an axon terminal, it causes the opening of calcium channels, which triggers fusion of neurotransmitter vesicles with the cell membrane
